How to install and tighten the hose clamp?

To install the hose clamp, first measure the size of the clamp required for your hose, and then select the appropriate clamp. According to the conditions of use, whether to choose embossed band clamps or perforated hose clamps. How to measure can refer to: How to choose the right size of the hose clamps? Match the type and size of the clamp to the diameter of the hose to be fixed. The width of the clamp should not exceed the hose connection, and the length of the band should be greater than the diameter of the hose, but it should not be too long. The extended part after clamping may cause the risk of scratching to the human body.


In order to install the hose clamp, first check all the necessary equipment, torque tester, electric torque screwdriver or slotted screwdriver, gloves etc,. Ordinary screwdrivers tend to slip out of the screw groove when tightening. It is recommended to use an electric torque screwdriver or a socket drive.


Loosen your hose clamp first and place it on the hose connection. Just turn the head of the worm gear screw counterclockwise to open the worm gear hose clamp. Use a screwdriver until the worm gear screw threads are loose from the slotted band. Pull the strap out of the worm gear housing so that it is close to the hose to open the strap. Place the worm gear hose clamp around the hose to be clamped with the worm gear screw head in the direction required to contact the head with the tool. Note that the screwdriver should be rotated concentrically for tightening. The hose should extend beyond the more parts of the hose clamp, otherwise the hose may slip off during the clamping process and the clamp may be twisted, resulting in a tight seal. If the connection part is short, a hose clamp with a smaller clamp bandwidth should be selected.


Install the hose clamp, check the tightening torque of the clamp, and use the screwdriver of the torque tester to check that the hose or tube is within the clamping range of the hose clamp. Measure the maximum and minimum diameters. Finally, make sure that the gloves are suitable. Control all the components. When using a screwdriver to tighten the hose clamp, it is recommended that the screwdriver should be vertical and not inclined to the screw head of the hose clamp. 


Torque Test


During the tightening process, the force will be biased towards the shell of the hose clamp, causing damage to the shell. Tightening when the maximum torque is reached once in a row, calibrate and stop the tightening. Do not break out multiple times in a row. Once the maximum torque is reached, the clamp should not be tightened again. Because of damage caused by incorrect tightening, the screwdriver should always be calibrated to match the component. Excessive tightening of the clamp will cause the clamp to cut into the hose or damage the clamp, causing problems such as damage or failure of the hose.
